NAME
     store, subyte, suswintr, suword - store data to user-space

SYNOPSIS
     #include <sys/types.h>
     #include <sys/time.h>
     #include <sys/systm.h>

     int
     subyte(void *base, int byte);

     int
     suword(void *base, long word);

     int
     suword16(void *base, int word);

     int
     suword32(void *base, int32_t word);

     int
     suword64(void *base, int64_t word);

     #include <sys/resourcevar.h>

     int
     suswintr(void *base, int word);

DESCRIPTION
     The store functions are designed to copy small amounts of data to user-
     space.

     The store routines provide the following functionality:

     subyte()    Stores a byte of data to the user-space address base.

     suword()    Stores a word of data to the user-space address base.

     suword16()  Stores 16 bits of data to the user-space address base.

     suword32()  Stores 32 bits of data to the user-space address base.

     suword64()  Stores 64 bits of data to the user-space address base.

     suswintr()  Stores a short word of data to the user-space address base.
                 This function is safe to call during an interrupt context.

RETURN VALUES
     The store functions return 0 on success or -1 on failure.
